    手机版万博注册登录载荷的计算 Calculation of the load of the roller 手机版万博注册登录载荷可分为静载荷和动载荷,工程设计中一般使用静力学和动力学两种计算方法。传统的设计中比较注重静特性计算,随着皮带输送机动力学分析的发展,工程技术人员在手机版万博注册登录设计的过程中也越来越注重动特性方面的考虑。 Roller load can be divided into static load and dynamic load. In engineering design, two methods of statics and dynamics are usually used. The traditional design pays more attention to the static characteristic calculation. With the development of the dynamic analysis of the belt conveyer, the engineers and technicians pay more attention to the consideration of the dynamic characteristics in the process of the design of the roller. 手机版万博注册登录的静载荷计算主要考虑传送物料和输送带自重对手机版万博注册登录产生的正向压力,在皮带弯曲段还应考虑输送带张力的作用,特别是在凹凸弧段。槽型手机版万博注册登录受力分析主要是载荷在3个手机版万博注册登录上的分配问题,尤其是在凸弧段,目前多数计算都把中间手机版万博注册登录看作是受力最大的,按物料重的70%和输送带重的40%计算,但是侧手机版万博注册登录受载后2个轴承的受力不等,同时还有比较大的轴向力。 The calculation of the static load of the roller mainly takes into account the positive pressure produced by the conveying material and the self weight of the conveyor belt. In the belt bending section, the effect of the tension of the conveyer belt should be considered, especially in the concave and convex arcs. The stress analysis of the groove roller is mainly the distribution of the load on the 3 rollers, especially in the convex arc section. Most of the calculation regards the middle roller as the maximum force, according to the weight of the material and the weight of the conveyor 40%, but the force of the 2 bearings after the side roller is loaded is not equal, and there is a relatively large axial force. 手机版万博注册登录的加工工艺及选择注意事项 Processing technology and selection attention of roller 手机版万博注册登录的动载荷是手机版万博注册登录实际选型中必须加以考虑的。手机版万博注册登录动载荷是由多方面的因素产生的,主要有: The dynamic load of idlers must be considered in the actual selection of idlers. The dynamic load of idlers is caused by many factors. ①手机版万博注册登录辊壳偏心转动时产生的动载荷; (1) the dynamic load generated by the eccentric roll of the roller housing. ②手机版万博注册登录偏心转动与输送带相互作用而产生的动载荷; (2) the dynamic load generated by the interaction between idler and the conveyor belt. ③输送带及物料运动时对手机版万博注册登录冲击产生的动载荷; (3) the dynamic load generated by the impact of the conveyor belt and the material during movement. ④输送带横向弯曲振动拍打手机版万博注册登录产生的动载荷; (4) the dynamic load caused by the transverse bending vibration of the conveyor belt. ⑤输送带张力变化对过渡段手机版万博注册登录、弯曲段手机版万博注册登录产生的动载荷; (5) the dynamic load caused by the tension change of the conveyor belt to the idler and bending section of the transition section. ⑥高速运行的输送带通过手机版万博注册登录时物料和输送带变形对侧手机版万博注册登录产生作用力,特别是物料中含有大块时其冲击力最大,目前这方面的研究还很少; (6) the high speed conveyer belt produces the force of the side roller through the deformation of the material and conveyor belt through the roller, especially when there is a large mass in the material, and the impact force is the most, so the research in this respect is very few at present. ⑦转载处手机版万博注册登录受物料下落的冲击动载 荷。正确地计算这些载荷对于选择手机版万博注册登录、估算手机版万博注册登录 的使用寿命是非常重要的。 The dynamic load of the roller at the retransmission place is affected by the falling of the material. Correctly calculating these loads is very important for selecting idlers and estimating the service life of idlers.
